fix(performer): tag chips → in-place horizontal filter selector

Follow-up to 1a4bf258 feedback (a627637b + 0264a3ff): the flexWrap chip list ate
too much vertical space and tapping navigated away to TagScenes. Rework: single-row
horizontal scroll of toggle-chips that filter the performer's scenes IN-PLACE
(performer_ids + tags in one listScenes query, no navigation). Selected chip is
highlighted with a ✕ affordance; tap again clears. One line tall instead of N rows.
